Analyzing any alternation in these markers couldgive valuable information, in relation to oral health status parameters. The aim of this study was to investigate thelevel of α -amylase in unstimulated whole saliva of healthy, primary school children in relation to some oral healthparameters.Materials and Methods: A questionnaires consisted of demography and medical histories of participants were filledby children families. Saliva samples were collected for 5- minutes between 9:00 -11:00 AM from 114 healthy studentsaged 6-13 years, divided into four age groups. Flow- rate, Plaque and Gingival Index were assessed and dentitionstatus was investigated by DMFT/dmft using WHO criteria. Salivary amylase was analyzed in unite per litter, usingquantitative colorimetric amylase determination at 585nm.Results: A significant positive correlation was found between age and salivary flow-rate, (r=0.362, P < 0.001). Salivaryα-amylase concentration increased significantly with age (P< 0.001). For each one year there is an increase in age,amylase level is expected to increase by 5.2 U/L. A male gender is expected to reduce salivary α -amylase level by10.6 U/L compared to female, however the effect was not significant. Gingival index was positively, although nonsignificantlyassociated with salivary α -amylase concentration. DMFT showed a significant weak positive linearcorrelation with salivary amylase level (r=0.309, P<0.001), while deciduous teeth decay experience and plaque indexwere significantly and negatively associated with salivary amylase.Conclusion: Results emphasize the importance of salivary amylase, as a non-invasive biomarker in regulating oraland dental health status in children
